There's no better place to start a day out in Windsor than at the castle.

If you time it right you might be lucky enough to see the Guard March at 10.50am, when you can watch the band go by as the guards march up the High Street.

Up close, the castle is even more beautiful than it looks from a distance. You can see why the 17th-century diarist Samuel Pepys claimed it to be the most romantic castle in the world.

Built by William the Conqueror after the Norman Conquest of 1066, it is one of the oldest royal residences still in use in the world.

Having the attention span of a gnat, keeping a seven-year-old occupied as you admire the great works of art, stunning gardens and amazing history might be difficult if it wasn't for the great audio commentary.

Once through the gates, we each collected what can only be described as a cross between a giant remote control and a mobile phone. You simply punch in the number corresponding to the room or area you are walking into, put it to your ear and listen to a description of what you are looking at.

Children have their own version, describing the same things but with different characters and all told as an interactive story. Alex virtually ignored us the whole way round, carefully putting the numbers in, listening to the story and walking around the rooms looking at the ceilings or special artefacts that were being pointed out to him. Much more fun than standing in a large group and straining to listen to a guide.

You need to allow at least two hours but probably not more than a half day to see everything.

Windsor Wheel

Next we took a ride on the Windsor Wheel. The views are breathtaking and on a clear day you can see as far as Wembley Stadium and even Canary Wharf!

It's very slick, very safe and completely enclosed so it doesn't matter if the weather isn't great.

French Brothers Boat Trip

Just across from the Wheel, you can jump on a boat run by French Brothers for a relaxing 40-minute ride along the Thames.

To be honest I think we'd have had more fun renting one of the little rowing or motor boats and guiding ourselves but with the threat of rain, this was the better option!

Eton College

Our last stop was Eton College, just over the bridge from Windsor.

Guided tours take place at 12.15pm and 3.15pm. We were taken round by a very down-to-earth gentleman who maintains the buildings and grounds at Eton.

The school was founded in 1440 by Henry VI and has educated 18 former British prime ministers! Annual fees are an eye-watering £20,000.

There was lots of exploring and not too much talking on the tour, which suited Alex as the end to a busy but really great day.
